STEAM-CONDENSER.

Specification of Letters Patent.

Application filed January 15, 1909.

Patented July 13, 1909.

Serial No. 472,531.

To all whom it may concern:

Be it known that I, GUs HARTMAN, a citizen of the United States, residing at Rockwall, in the county of Rockwall and State of Texas, have invented a new and useful Steam-Condenser, of which the following is a specification.

This invention relates to that type of steam condensers known as surface condensers, and it has for its object to provide an apparatus of this kind which is simple and inexpensive in construction, and also one which. is highly efficient in operation.

With the foregoing objects in view the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the drawing hereto annexed, in which z- Figure 1 is a central vertical section of the condenser. Fig. 2 is a horizontal section on the line 22 of Fig. 1.

Referring more specifically to the drawing, 5 denotes the exhaust pi e on which is mounted the apparatus am into which said pipe discharges. A short distance below the mouth of this pipe is mounted a platform 6, said platform being secured to the pipe in any suitable manner.

The casing of the apparatus has an outer cylindrical shell 7, and a bottom 8 closing the lower end thereof. The casing also contains a false bottom 9, which is uniformly inclined from the center, or, in other words, is made conical. Extending from the bottom 8 to the false bottom 9 at the center thereof is a tube 10, through which the exhaust pipe 5 enters the condenser casing, the diameter of said tube being such that the exhaust pipe fits snugly therein. The condenser is supported on the exhaust pipe by resting on the platform 6. Close to the base of the false bottom 9 are perforations 11, and the bottom 8 is provided with an outlet 12.

Within the shell 7 is mounted, concentric therewith, an inner cylindrical shell 13, which is in axial alinement with the exhaust pipe. The lower end of this inner shell is spaced from the bottom of the condenser casing. The inner shell is open at both ends, and over its outer end extends a hood 14, which is in the shape of a cone.

The space between the inner and outer shells is sufhcient to accommodate an inner and outer circular series of fines 15 and 16,

respectively. These flues extend lengthwise through the space and are secured at their ends to flue-plates 17 closing the ends of the space. Both sets of fines are open at their ends, and open, at their lower ends, into the condenser casing, opposite the false bottom 11. The inner set 15 of the flues open at their upper ends into the hood 14, and the outer flues 16 open, at their upper ends, to the atmosphere.

The space between the inner and outer shells forms a chamber to receive a cooling medium, such as water, which surrounds the flues 15 and 16. The water enters this chamber at the lower end thereof through a series of pipes 18, arranged in the form of a cross, as shown in Fig. 2 of the drawing, and extending transversely from one side of the condenser to the other, through the chamber. Within the chamber, the pipes are provided with perforations 19, through which the water discharges into the chamber. All of the supply pipes 18 are closed at their outer ends, with the exception of one, which is connected to the source of supply. The outlet for the cooling medium is a pipe 20, entering the chamber at the upper end thereof, through the outer shell 7.

At 21 is indicated a nipple on the outer shell 7, which is for the purpose of a pipe connection with the boiler feed pump, if the apparatus is also to be used as a feed water heater.

The operation of the condenser is as follows :The steam issuing from the exhaust pipe 5 passes up the large central flue formed by the inner shell 13, and, upon striking the hood 14, is deflected downwardly and passes through the inner set of lines 15, and as said fines are surrounded by a cooling medium, the steam is rapidly condensed and drops down on the false bottom 9 and flows through the openings 11 therein to the outlet 12. The outer lines 16 permit the escape of any surplus steam which might accumulate in the condenser.

What is claimed is 1. In a steam condenser, a casing comprising an outer shell and a bottom closing the lower end thereof, a conical false bottom rising from said bottom, and having perforations adjacent to its base, a series of return fiues in the casing, a portion of said fines opening to the atmosphere, a chamber surrounding the fiues, means for introducing a cooling medium into said chamber, an inlet atmosphere, and means for surrounding said to the casing, and a discharge pipe connected flues with a cooling medium.

to the bottom thereof below the false bottom.

2. A steam condenser comprising a casing having an inlet, and an inclined false bottom provided with outlet openings, a discharge pipe connected to the casing below the false bottom, a series of return flues in the casing, a chamber surrounding said flues, and means for introducing a cooling medium into said chamber.

3. A steam condenser comprising a closed casing containing a central flue and having an inlet discharging into one end of said flue, a-hood over the other end of the flue, a series of flues surrounding the central flue, and opening at one end into the casing, and at the other end into the hood, and means for sur rounding said series 01' flues with a cooling medium.

4. A steam condenser comprising a closed casing containing a central flue, and having an inclined bottom provided with an inlet discharging into one end of said flue, and outlets, a hood over the other end of the flue, a series of flues surrounding the central flue and. opening at one end into the casing, and at the other end into the hood, and means for surrounding said series of flues with a cooling medium.

5. A steam condenser comprising a closed casing containing a central flue, and having an inlet discharging into one end of said flue, a hood over the other end 01' the flue, a series of flues surrounding the centralflue and opening at one end into the casing, a portion of said flues opening at the other end into the hood, and the other portion opening to the 6. A steam condenser comprising spaced outer and inner shells, the inner shell being open at its ends, and the outer shell extending at one end below the inner shell, and being closed at said end, with an inlet therein, a hood over the other end of the inner shell, a closure for the ends of the space between the shells, means for introducing a cooling medium into said space, and a series of flues passing through said space and opening through the closed ends thereof, a portion of said flues opening, at their upper ends, into the hood and the other portion opening to the atmosphere.

7. A steam condenser comprising spaced outer and inner shells, the inner shell being open at its ends, and the outer shell extending at one end below the inner shell, and being closed at said end, with an inlet therein, a hood over the outer end of the inner shell, a closure for the ends of the space between the shells, means for introducing a cooling medium into said space, and an inner and an outer series of flues passing through said space, and opening through the closed ends thereof, the inner series of tubes opening into the hood and outer series opening to the atmosphere.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
